Abstract
Flood risk assessment is important for decisionmaking in flood management strategies and countermeasures. In this paper, an index systemincluding one integrated index, three component indices, and eight basic indices is first introduced. Then a simple model based on the index system is formulated for assessing flood risks in the mid- and macro-scale regions. Two methods, namely Normal Distribution Reference and Hazard-Vulnerability Block, are used thereafter to define threshold values of risk levels. A macrostrategy for flood management is finally developed based on computed flood risk levels. A case study was carried out for flood risk assessment at the county level in Fujian province, China, and simulation results matched with local relief and historical flood records well.
